FLIER SPINNING, TWISTING, AND SIMILAR MACHINE.

Application filed J'une- 6, 1914. Serialllo. 843,529.

To all whom it may concern:

Be it known that I, ROBERT HAMPE, manufacturer, citizen of the Duchy ofBrunswick, residing at Helmstedt, Germany, have invented certain new anduseful Improvements in Flier Spinning, Twisting, and Similar Machines,of which the following is a specification.

My invention relates to improvements in flier spinning, twisting andsimilar machines, and more particularly in machines in which the flierspindles are mounted in stationary bearings. In machines of this classthe pegs, bells, or the like for the supply of empty bobbins and the forthe reception of full bobbins from the flier spindles are disposed intwo or more rows which are immovable relatively to each other andmounted on specialsupporting members, such for example as two parallelrails connecting the supporting members, and the said supports or railshave been so mounted as to be horizontally and vertically movable insuch a way that the pegs or bells orthe like of the bobbins can bepositioned coaxially of the spindles of the fliers. In order tovertically move the supporting member, which is necessary in order toremove the rails carrying the bobbins and the foot step bearings,comparatively much power is necessary, because the supporting member andthe pegs, bells, or the like which are mounted thereon are comparativelyheavy. Thereby the operation of the apparatus for exchanging the bobbinsis made inconvenient.

The object of the improvements is to provide amachine of this class inwhich it is not necessary to shift the supporting members and the bobbinpegs or the bells provided in lieu thereof in vertical direction, forwhich purpose the rail which imparts vertical reciprocating movement tothe bobbins during the spinning operation and in some cases also therail carrying the foot step bearings of the flier spindles is mountedfor vertical shifting movement on the supporting members or the guidesthereof, while the supporting members are so mounted as to be incapableof vertical shifting movement and located so low, that the members suchas pegs or bells which carry the bobbins can be brought in alinementwith flier spindles simply by the horizontal displacement of the saidsupporting members. Thereby the construction and the operationSpecification of Letters Patent.

of the mechanism for exchanging the bobbins are made more simple.Furthermore the improved mechanism is particularly suitable whenreconstructing old spinning machines.

For the purpose of explaining the invention several examples embodyingthe same have been shown in the accompanying drawings, in which the sameletters of reference have been used'in all the views to indicatecorresponding parts.

In sa d drawingsFigure '1, is a front view of the flier spinning machineprovided with my improved apparatus for exchanging the bobbins, Fig. 2,is a partial plan view of the machine shown in Fig. 1, Figs. 3 and 4,arefront views showing a modification of the machine with the parts indifl erent positions, and Fig. 5, is a view similar to that shown inFig. l with some arts removed and showing a further modification.

frame of the machine consists of a plurality of uprightsl each carryingon a bracket 2 a horizontal guide rod 3 providing a support for a slide4. The slides carry at their outer ends a rail or plate 7 to which tworows of bobbin pegs 8 and 9 are secured so as to be nonshiftablerelatively to each other. By shifting the slides 4 on their rods 3 thepegs 8 and 9 can be set in alinement with the spindles of the fliers 18for exchangingthe bobbins. As shown in the drawings the slides 4 areshifted by means of a shaft 14 mounted on the machine frame 1, and pro-In the example shown in Figs. 1 and 2 the vided with gear wheels 13 onefor each of x the slides 4. Each of the gear wheels is in mesh with rackteeth 4 provided on the cooperating slide. The shaft 14 is adapted to berotated by suitable means such as a hand crank.

To the slides 4 vertical sleeves 5 are secured which provide guides forrack bars 6 formed with rack teeth. On the upper end of the said rackbars 6 a lifter rail 30 is wheels 12 are keyed with the rack bars 6. Asis shown in Fig. 2 the foot step rail 34 is provided with open portions31 which permit the passage of the. pillars 1 therethrough when shiftingthe slides 1 to the right inFig. 1. Similar open portions are providedin the lifter rail 30.

On the pillars 1 slides 25 are mounted which are adapted to be shiftedin vertical direction by means of gearings 16 and 28, the said slidecarrying a shaft 27. To the said shaft arms 29 are secured which areprovided for holding the full bobbins and lifting the empty ones. Theslide 25 is formed in such a way, that the arms 29 do not extend intothe paths of the fliers 18. Therefore it is not necessary to readjustthe fliers 18 prior to dotting the bobbins. By means of the verticallymovable lifter rail 30 the full bobbins are smoothly lowered, so thatthe threads 55 can be wound only on the lowermost part of the flierspindles.

The lifter rail 30 which continuously lifts and lowers the bobbins whilethe machine is in operation and which is located above the foot steprail 31, is provided with engaging devices 31 one for each of thespindles 18. lVhen the rail 30 is moving downward and on to the footstep rail 31 the said engaging devices move upward relatively to therail 30 and thereby raise the bobbins 4.7 from the drag washers 32of'the rail 30 to such an extent, that the arms 29 can easily engagebelow the flanges 117' of the bobbins. Therefore all that is necessaryin my improved machine for dofling is to shift the foot step rail31together with the lifter rail 30 which has before been lowered on thesame, and to horizontally shift the slides -1 with the said rails.

lVhere the spindles are freely suspended and are not provided with footstep bearings, the foot step rail 31 can be rigidly secured to thesleeves 5. In this case the. only object of the rail 31 is to lift theengaging devices 31 mounted on the lifter rail, so that the flanges ofthe bobbins are disengaged, the sockets 31 striking on the foot steprail 31 and moving upward beyond the lifter rail 30 when the latter ismoved downward. In this operation they lift the lower bobbin flanges 17from the drag washers 32 of ,the rail 30, so that the arms 29 can easilyengage below the flanges 17.

In the example shown in Figs. 1 and 2 the bearings -18 of the fliers 18are suspended from the overhead rail 50 of the machine by means of ballsor rollers 49 which are lo cated diametrically opposite each other atopposite sides of the bearings 18, the latter being provided with twonotches which are open downward and the overhead rail 50 being providedwith corresponding notches which are open at their top sides. By reasonof this suspension of the fliers 18 the latter vas the rails 30 or 31moving upward, the

spindles can yield a little so that injury of the parts is avoided. Asis shown in. Fig. 1 the driving belts 51 for the fliers 18 pass throughopenings 50 of the overhead rail 50. Thereby the driving belts 51 areprotectcd against the dust, hairs and the like which fall from thefeeding mechanism Besides the construction of the spinning machine isthereby made more simple.

For severing the thread when dotting and after an empty bobbin 17 hasbeen placed 011 one of the fliers 18 and the latter has performed a'fewrevolutions for the purpose of attaching the end of the thread to theempty bobbin, severing mechanism of known construction may be provided.In the example shown in the drawings the said severing mechanismconsists of a pair of cutter blades 38 and 38 adapted to be shiftedtoward and away from each other by the hand of the operator after .thecutting mechanism has been raised to such an extent, that the threads 55which are passed from the empty bobbins placed on the fliers 18 to thefull bobbins on the pegs 9 extend between the cutting edges of thecutter blades 38 and 38.

In Figs. 3 and -l I have shown mechanism for providing an accurate guidefor the foot step rail 31 in Figs. 1 and 2. As shown the foot step rail31 is normally held in operative position by means of springs 40 thepower of which is such that they just overcome the weight of the rail 31and yield when the lifter rail 30 is lowered on the rail 34, as is shownin Fig. 1. To the supporting members or bridges l or the rail 7 carriedthereby brackets 35 are secured on which shafts 39 are mounted forvertical reciprocating movement. On the said shafts the springs -10 arecoiled which engage. below collars 11 and press the shafts39 and thefoot step rail upward to such an extent that the spindles 18 engage inthe proper way in the foot step bearings 42.

For severing the threads when dofling a severing mechanism 38", 38 maybe provided.

Instead of the bridges 4 shown in Figs.

1 and 2 which are movable in horizontaldirection carrying members maybeprovided which have rocking supports on a stationary horizontal shaft,and which provide supports for the foot step rail 34. This constructionis shown in Fig. 5. Each of the carrying members is in the form of a1101- rails 30' and 34' which are adapted to be raised and lowered bymeans of racks 6 the rails 30 can pass into the hollow of the ring. Inthis position the part of the ring which carries the pegs 8 and. 9 movesbeyond and 34 when the ring 56 is being turned. In the example shown inthe figure the ring is adapted to be turned by means of a gear wheel 13engaging in rack teeth 56 provided on the ring 56, the gear wheel 13being adapted to be turned by means of aremovable crank 57 or the like.Common driving means may be pro vided for all the rings 56,.in whichcase all the gear wheels 13 are. secured to a common shaft 1 1.

Any known or preferred means may be provided for supporting the ring 56.i To show what may be done the ring 56 is rotata-bly mounted on a core58 which is rigidly secured to the frame 1' of the machine and isprovided with an open portion 58' for the reception of the rails 30' and34.

The operation of the dofiing mechanism is the same as in ordinarymachines, so that a detailed description is not necessary. For removingthe full bobbins 47 from the pegs 9' after severing the threads 55 acarriage 59 may be provided which is supported with its wheels 60 onlongitudinal rails 61 provided alongside the machine. When the saidcarriage is moved by the operator along the machine the full bobbins arecollected from the pegs 9 by means of a stripping member 62 or the like.

The position which the parts assume during the spinning operation isrepresented in Fig. During the spinning operation the spool rail 30rises and depresses alternately by means ofthe gear wheel 12 and rack 6shown in Fig. 1, the wheel 12 being turned alternately by the weightedrope 45 engaging the pulley 10 mounted on the shaft 11 and by the cam 43through the actuation of the lever 41 carrying a roller engaging saidlatter cam. If full spools are to be replaced by empty ones, the partsof the fliers 18 are first disposed in alinement, see Fig. l. The spoolrail 30 is then lowered until it comes in contact with the bearing rail34:, this operation being effected by the lowering movement of theweighted rope 45 engaging the pulley 10. Then the spool rail 30 descendsit carries the foot bearing rail 34 downwardly therewith for a shortdistance against the tension of spring *0, as shown by Fig. 4, andthereupon the hook 29, Fig.

hook being swung around the shaft 27, and

after this latter engagement of the hook with the spool has ensued thesaid hook and spool are slightly lifted by means of gear 28 and rack 16.The carriage at is now moved to the right by the operatlon of the pinion14 and rack 4, the movement of the said carriage being to such an extentas to place the spool pin 9 under the spindle 18. The hook 29 isreleased from the spool and the latter falls and is caught on the pin 9.The carriage 1 immediately following the latter operation is displacedslightly to the left or until the pin 8 carrying the empty spool ismoved under the spindle 18. The hook 29 is then caused to engage underthe upper flange of the empty spool 47, as shown by Fig. 1, and the saidempty spool is moved upwardly until it is pushed upon the spindle 18.The carriage 4c is next shifted to a greater distancev to the left orinto the position shown by Fig. 1 and the spool rail 30 is again raisedwhereby the foot bearing The thread is first wound to some extentv uponthe empty spool and is then cut off in a Well known manner.
